DISMOUNTING MOUNTINGIf the valve is already installed on the line, shut-off the fluid flow upstream and make sure that there is no pressure. If necessary, fully drain the system downstream. If there are hazardous fluids present, drain and ventilate the valve.

The diaphragm constitutes the part of the valve more subject to mechanical and chemical stress from the fluid. Consequently, the condition of the diaphragm must be checked at regular intervals in accordance with the service conditions. To do this, it must be disconnected from the handwheel and from the valve body.

1) Unscrew the four screws (5) and separate the body (1) from the internal components.

2) Unscrew the diaphragm seal (2) from the shutter (7).

3) If necessary, clean or replace the diaphragm seal (2).

4) If necessary, lubricate the stem (9).

1) The diaphragm seal (2) must be screwed fully into the compressor (7) in a clockwise direction. If necessary, unscrew slightly in an anticlockwise direction to line up the screw holes.

2) Fix the bonnet (10) to the body (1) using screws (5). Tighten the screws, making sure not to over-compress the diaphragm.

INSTALLATIONThe valve can be installed in any position and in any direction.When starting up the plant, make sure that there are no leaks from between the diaphragm and the valve body. If necessary, tighten the fastening screws (5).

SETTING

The valve is factory set to guarantee a permanent seal without requiring any further intervention. To adjust the setting, rotate the handwheel to the required minimum opening position, remove screw (26) using a hex key.

Remove the bonnet (25) and rotate the handwheel (23) clockwise until a resistance to the rotation is felt.

If necessary, replace the O-Ring (24) in its seating and re-insert the bonnet

(25) in the handwheel: the double D connection must fit over the stem (9) and, with a slight twisting action, align the ribs in the bonnet with those in the handwheel.

Tighten screw (26) to a sufficiently high torque value.

Each turn of the handwheel corresponds to 1.75mm travel.

882

The new 882 diaphragm valve is particularly suitable for shutting off and regulating abrasive or dirty fluids. The new internal geometry of the body optimises fluid dynamic efficiency by increasing the flow rate and ensuring an optimum linearity of the flow adjustment curve. The 882 is extremely compact and very light. The innovative handwheel is equipped with a patented immediate and ergonomic operating locking device that allows it to be adjusted and locked in any position.

2-WAY DIAPHRAGM VALVE

• Connection system for solvent weld, threaded and flanged joints

• optimised fluid dynamic design: maximum output flow rate thanks to the optimised efficiency of the fluid dynamics that characterise the new internal geometry of the body

• Internal components in metal, totally isolated from the fluid and external en-vironment

• Modularity of the range: only 2 handwheel and 4 diaphragm and bonnet sizes for 7 different valve sizes

• Non-rising handwheel that stays at the same height during rotation, equipped with a graduated optical indicator protected by a transparent PVC cap with seal O-Ring

• Bonnet fastening screws in AISI 316 steel protected against the external envi-ronment by PE plugs. Absence of metal parts exposed to the external envi-ronment to prevent any risk of corrosion

• CDSA (Circular Diaphragm Sealing Angle) system that, thanks to the uniform distribution of shutter pressure on the diaphragm seal, offers the following advantages:- reduction in the tightening torque of the screws fixing the actuator to the

valve body- reduced mechanical stress on all valve components (actuator, body and dia-

phragm)- easy to clean valve interior- low risk of the accumulation of deposits, contamination or damage to the

diaphragm due to crystallisation- operating torque reduction

4 Handwheel and bonnet in high mechanical strength and chemically resistant PP-GR, providing full protection by isolating all internal metal parts from contact with external agents

5 Floating pin connection between the control screw and diaphragm to prevent concentrated loads, improve the seal and extend its lifetime

6 New design of valve body interior: substantially increased flow coefficient and reduced pressure drop. The degree of efficiency reached has also enabled the size and weight of the valve to be reduced

7 Adjustment linearity: the internal profiles of the valve also greatly improve its characteristic curve, resulting in extremely sensitive and precise adjustment along the entire stroke of the shutter

8 Valve anchoring bracket integrated in the body, with threaded metal inserts allowing simple panel or wall mounting using the wall mounting plate (supplied as an accessory)

FASTENINg AND SUPPORTINgAll valves, whether manual or actuated, must be adequately supported in many applications.

The 882 valve series is therefore provided with an integrated bracket that permits direct anchoring of the valve body without the need of other components.

For wall installation, dedicated wall mounting plates which are available as accessories can be used. These plates should be fastened to the valve before wall installation.

The wall plate also allows the 882 valve to be aligned with SED pipe clips.

CUSTOMIzATIONThe 882 DN 15-65 valve can be customised using a customization plate in white PVC.

The customization plate (B), housed in the transparent protection cap (A), can be removed and, once overturned, used for indicating identification serial numbers or service indications on the valves such as, for example, the valve function in the system, the conveyed fluid, but also specific information for customer service, such as the customer name or installation date or location on the valves. The waterproof transparent protection cap with seal O-Ring protect the customization plate against deterioration.

To access the customization plate, make sure that the handwheel is in the release position and proceed as follows:

1) Rotate the transparent protection cap fully anticlockwise (fig. 1) and remove it by pulling upwards. If necessary, insert a screwdriver in slot (C) to make the operation easier (fig. 2).

2) Remove the plate from inside the transparent protection cap and customise as required (fig. 3).

3) Re-assemble everything making sure that the transparent protection cap O-Ring remains in its seating fig. 4).

DISASSEMBLY ASSEMBLY 1) Isolate the valve from the line (re-

lease the pressure and empty the pipeline).

2) If necessary, release the handwheel by pressing downwards (fig.5) and rotating anticlockwise to fully open the valve.

3) Unscrew the union nuts (11) and ex-tract the valve sideways.

4) Remove the protection plugs (14) and bolts (13) with the relative wash-ers (12).

5) Separate the valve body (8) from the internal components (4).

6) Rotate the handwheel clockwise to free the threaded stem (5), compres-sor (6) and diaphragm (7)

7) Unscrew the diaphragm (7) and re-move the shutter (6).

1) Insert the compressor (6) on the threaded stem (5) aligning it correct-ly with the reference pin on the stem.

2) Screw the diaphragm (7) on the threaded stem (5).

3) Lubricate the threaded stem (5), insert it in the operating mecha-nism (4) and rotate the handwheel anticlockwise until the stem is fully screwed in (5).

Make sure that the compressor (6) and diaphragm are correctly aligned with the housings in the operating mechanism (4) (fig. 7).

4) Fit the operating mechanism (4) on the valve body (8) and tighten the bolts (13) with the relative washers (12).

5) Tighten the bolts (13) evenly (di-agonally) to the tightening torque suggested on the relative instruction sheet.

6) Replace the protection plugs (14)7) Position the valve body between the

end connectors (10) and tighten the union nuts (11), making sure that the socket seal O-rings (9) do not exit their seats.

8) If necessary, block the handwheel by grasping it and pulling it upwards (fig. 6).

Note: during assembly, it is advisable to lubricate the threaded stem. Mineral oils are not recommended for this task as they react aggressively with EPDM rubber.

INSTALLATIONBefore proceeding with installation. please follow these instructions carefully: (these instructions refer to union end versions). The valve can be installed in any po-sition and in any direction.

1) Check that the pipes to be connected to the valve are aligned in order to avoid mechanical stress on the threaded joints.

2) Unscrew the union nuts (11) and insert them on the pipe segments.

3) Solvent weld or screw the end connectors (10) onto the pipe ends.

4) Position the valve body between the end connectors, making sure that the sock-et seal O-rings (9) do not exit their seats.

5) Fully tighten the union nuts (11).

6) If necessary, support the pipework with SED pipe clips or by means of the carrier built into the valve itself (see paragraph “Fastening and supporting”).

Note: Before putting the valve into service, check that the bolts on the valve body (13) are tightened correctly at the suggested torque.

ADjUSTMENT

The 882 valve is equipped with a handwheel locking system that prevents the valve from being operated.The system can be engaged by simply lifting the handwheel once the required position has been reached (fig. 8).To release the operating mechanism, simply return the handwheel to its previous posi-tion by pushing it downwards (fig. 6).When the system is in the locked position, a lock can be installed to protect the plant against unwanted interference (fig. 9).

The version of the diaphragm valve equipped with a handwheel stroke control system allows the minimum and maximum flows to be preset.The system allows the valve stroke to be modified using the two independent adjusting screws, which determine the mechanical limits of the valve during opening and closing. The valve is sold with the stroke limiters positioned such that does not limit the open-ing or closing stroke.To access and set the adjusting screws, remove the transparent protection cap (A) as previously described (see chapter “Customization”).

Travel stop adjustment. Minimum flow rate

1) Rotate the handwheel clockwise until the required minimum flow rate is reached.

2) Screw in nut (D) as far as it will go and lock it in this position by tightening the lock-nut (E).

If it is not necessary to limit the closing stroke, completely unscrew nuts (D and E). In this way, the valve will fully close.

3) Re-assemble the transparent protection cap making sure that the seal O-Ring re-mains in its seating.

Stroke limiter adjustment. Maximum flow rate

1) Rotate the handwheel anticlockwise until the required maximum flow rate is reached.

2) Rotate knob (F) anticlockwise as far as the stop. The plate indicates the direction of rotation of the wheel required to obtain a higher or lower maximum flow rate.

If the opening stroke does not need to be limited, rotate the knob (F) clockwise a number of times. In this way, the valve will fully open.

3) Re-assemble the transparent protection cap making sure that the seal O-Ring re-mains in its seating.

885

The 885 is particularly suitable for shutting off and regulating abrasive or dirty fluids. The handwheel control and diaphragm seal provide precise and effective control, while reducing the risk of water hammer to a minimum.

2-WAY DIAPHRAGM VALVE

• Connection system for solvent weld, threaded and flanged joints

• Compact and lightweight construction

• High flow coefficient and minimum pressure drop

• Internal components in metal, totally isolated from the conveyed fluid, with anti-friction disk to reduce friction to a minimum

• Modularity of the range: only 2 handwheel and 2 diaphragm and bonnet sizes for 2 different valve sizes

• Handwheel that stays at the same height during rotation

• Bonnet fastening screws that crew into the built-in bush preventing the de-posit of dirt or impurities

• CDSA (Circular Diaphragm Sealing Angle) system that, thanks to the uniform distribution of shutter pressure on the diaphragm seal, offers the following advantages:

- reduction in the tightening torque of the screws fixing the actuator to the valve body

- reduced mechanical stress on all valve components (actuator, body and dia-phragm)

- easy to clean valve interior

- low risk of the accumulation of deposits, contamination or damage to the dia-phragm due to crystallisation

- operating torque reduction

INSTALLATIONThe valve can be installed in any position and in any direction.When starting up the plant, make sure that there are no leaks from between thediaphragm and the valve body. If necessary, tighten the fastening screws (9).

If the valve is already installedon the line, shut-off the fluid flowupstream and make sure thatthere is no pressure. If necessary,fully drain the system downstream. Ifthere are hazardous fluids present, drainand ventilate the valve.The diaphragm constitutes the partof the valve more subject to mechanicaland chemical stress from the fluid.Consequently, the condition of thediaphragm must be checked at regularintervals in accordance with the serviceconditions. To do this, it must bedisconnected from the handwheel andfrom the valve body1) Unscrew the four screws (9) and separate the body (8) from the internal components.2) Unscrew the diaphragm (7) from the shutter (6). Rotate the handwheel clockwise to free the stem-shutter unit.3) If necessary, clean or replace the diaphragm (7).4) If necessary, lubricate the stem (4).

1) Insert the handwheel in the bonnet (2)2) The ball bearing (3) must be positioned on the sleeve over the bonnet. To ensure a perfect seal, use a liquid sealing compound such as Loctite.3) Subsequently, the shutter (6) must be removed from the stem (4) and fixed using the pin. Warning: the pin must be well secured in the seating hole in the stem.4) The stem (4) must now be screwed to the threaded sleeve. Warning: lefthand thread. The shutter (6) must be oriented such that the guide pins correspond with the grooves in the bonnet.5) The shutter (6) must be fully tightened on the bonnet by rotating the handhweel. Then, the diaphragm (7) must be screwed fully into the bonnet and then rotated in the opposite direction until the holes in the diaphragm coincides with the holes in the bonnet.6) Place the bonnet with the diaphragm in the correct position in the body (8). Fix the protection plugs (10) using the hexagonal screws and washers (12). Tighten evenly (cross-like).
